what is the difference between electric energy and electric power
Answers
Answer:
Two differences between electric energy and electric power are : Electrical power is the rate of amount of electrical energy transferred. Electrical energy is the energy generated as the result of the potential difference in a circuit which causes current to flow through it. Energy is measured in joules.
hope it will help
Answer:
➥ Electric Energy:
Potential difference is a measure of work done in moving a unit charge and current is the amount of charge flowing in one second.
Therefore:
Work Done (W) = Potential difference (V) × Amount of charge(Q)
= Potential Difference × Current (I) × Time (t)
= VIt
= I²Rt
= V²/R × t
[ V = IR, Ohm's law ]
➥ Electric Power:
Power is the rate of doing work, or the rate at which energy is produced.
P = Energy released/time
= VIt/t
= VI
- Electric power can be defined as "the Electric work done per unit time" or "the rate of consumption of electric energy in a circuit".
Electric Power (P) = Electric work done/time
= w/t
Extra Dose:
- The SI unit of Electric power is watt.
- 1 watt = 1 joule/sec
- 1 kilowatt ( kW) = 1000 W = 10³ W
- 1 Megawatts (MW) = 1000000W
